Exfoliation/delamination of kaolinite by low ... ScienceDirect
The effects of short milling (2 × 10 min) of two fractions of kaolinite (< 5 μm (S5) and 545 μm (S)), previously expanded by intercalation with 20 wt.% and 40 wt.% urea (U) and exfoliated/delaminated using lowtemperature procedures, were studied. Untreated and treated kaolinite samples were examined by Xray powder diffraction (XRPD), and their specific surface area (SSA), particle size ...
